CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. patent application Ser. No. 14/886,203 filed Oct. 19, 2015, which claims the benefit of and priority to U.S. Provisional Patent Application No. 62/100,632, filed Jan. 7, 2015, the entire disclosure of which is incorporated by reference herein.

BACKGROUND Technical Field

The present disclosure relates to surgical clip appliers. More particularly, the present disclosure relates to reposable endoscopic surgical clip appliers.

Description of Related Art

Clip appliers are used in surgical procedures to apply a surgical clip to a blood vessel or another duct to prevent the flow of body fluids therethrough. Clip appliers are used during a variety of surgical procedures, some of which include, open surgery, endoscopic procedures, and robotically controlled procedures. Clip appliers that apply multiple clips generally provide a plurality of surgical clips stored in a clip cartridge mounted at the distal end of the clip applier. The clips from the clip cartridge are fed sequentially to jaws defined by a jaw blade at the distal end of the instrument upon actuation of handles at the proximal end of the instrument. As the handles are closed, the jaws close to deform a surgical clip positioned between the jaws, and as the jaws are opened to release the deformed surgical clip, a new surgical clip is fed from the clip cartridge to a position between the jaws. This process is repeated until all the surgical clips in the clip cartridge have been applied. A new clip cartridge can then be positioned on the clip applier.

Some clip appliers include complicated internal structure(s) that prevent effective re-sterilization and are therefore single use, disposable instruments. Reposable clip appliers are instruments having a body that can be re-sterilized and re-used a number of times. It would be desirable to provide improved clip cartridge and jaw blade components for a reposable surgical clip applier to facilitate simple and easy disassembly and re-assembly of the instrument during sterilization.

DETAILED DESCRIPTION

Embodiments of a surgical clip applier in accordance with the present disclosure will now be described in detail with reference to the drawing figures wherein like reference numerals identify similar or identical structural elements. As shown in the drawings and described throughout the following description, as is traditional when referring to relative positioning on a surgical instrument, the term “proximal” refers to the end of the apparatus which is closer to the user and the term “distal” refers to the end of the apparatus which is further away from the user.

Referring briefly to FIGS. 1-3, a surgical clip applier in accordance with the present disclosure is generally designated as 100. Surgical Clip applier 100 generally includes an actuation mechanism and a body portion 110 extending distally from the actuation mechanism. The actuation mechanism may take a variety of forms, such as, a handle assembly or a robotically assisted surgical system which permits remote operation and control of surgical instruments.

With reference to FIGS. 1-3, an embodiment of surgical clip applier 100 including a handle assembly 102, will be described. Handle assembly 102 includes a moveable handle 104 and a stationary hand grip 106. Handle assembly 102 supports a body portion 110 having a proximal end 112 and a distal end 114. The body portion defines an open cavity 116 disposed at or near distal end 114 thereof. Surgical clip applier 100 includes or is capable of receiving a clip cartridge 150 and a jaw blade 160 in cavity 116 disposed at distal end 114 of the body portion 110. Clip cartridge 150 and jaw blade 160 are both removable from within open cavity 116 of body portion 110. During use, multiple surgical clips are typically loaded and/or retained within clip cartridge 150. Clip cartridge 150 and jaw blade 160 are disposed within the open cavity 116 at the distal end 114 of the body portion 110, and upon actuation of the moveable handle 104 in direction “A”, towards stationary hand grip 106, clip cartridge 150 and jaw blade 160 cooperatively engage to load a unformed surgical clip between first and second jaw sections 192, 194 of the jaw blade 160 and clamp a surgical clip. A complete description of the inner-workings and operation of an exemplary surgical clip applier 100 can be found in commonly-assigned U.S. Patent Publication No. 2008/0243145 A1 to Whitfield et. al., the entire contents of which are hereby incorporated by reference herein.

Referring briefly to FIG. 4A, a cross-sectional view of the distal end 114 of the body portion 110 is shown without clip cartridge 150 installed. Jaw blade 160 is disposed at the distal end 114 such that a portion of jaw blade 160 extends past the distal end 114 of the body portion 110.

Turning now to FIG. 5, clip cartridge 150 includes a first extrusion or nub 152 and a second extrusion or nub 154 extending from a channel, body, or the like 151 of clip cartridge 150. First nub 152 and second nub 154 are longitudinally spaced apart from one another and protrude in a common direction from body 151 of clip cartridge 150.

As seen in FIGS. 6 and 8, jaw blade 160 includes a shank section 162 having a first end 164 and a second end 166, a first leg member 170 which extends distally from the second end 166 of the shank section 162, and a second leg member 180 which extends distally from the second end 166 of the shank section 162. In embodiments, first and second leg members 170, 180 are symmetrically disposed along longitudinal axis “A” defined by jaw blade 160. First leg member 170 and second leg member 180 have a respective proximal end 172, 182, and a respective distal end 174, 184. Jaw blade 160 further includes a first jaw section 192 and a second jaw section 194, which together form or define jaw 190. First jaw section 192 and second jaw section 194 are disposed at the distal end 174, 184 of the first and section leg member, 170, 180, respectively. During actuation of the actuation mechanism, the first jaw section 192 and second jaw section 194 of jaw 190 come together to clamp or form a surgical clip “C” disposed or loaded therebetween as shown in FIG. 4A.

With reference to FIGS. 7 and 8, the interaction of clip cartridge 150 and jaw blade 160 are described. In one embodiment of the present disclosure, with jaw blade 160 mounted within open cavity 116 at the distal end 114 of the body portion 110, and clip cartridge 150 loaded into open cavity 116 at the distal end 114 of the body portion 110, the first nub 152 of clip cartridge 150 abuts the first end 164 of the shank section 162 of jaw blade 160 while the second nub 154 of clip cartridge 150 abuts the second end 166 of the shank section 162 of jaw blade 160 such that the second nub 154 of clip cartridge 150 extends between the proximal end 172, 182 of first and second leg member 170, 180, respectively. Once clip cartridge 150 and jaw blade 160 are disposed or loaded into the open cavity 116 at the distal end 114 of the body portion 110, first and second nubs 152, 154 of clip cartridge 150 act to arrest, prevent, or otherwise block longitudinal and vertical movement of the jaw blade 160 while still allowing first and second jaw sections 192, 194 to open and close to form a surgical clip “C” positioned therebetween.

Specifically, when jaw blade 160 is coupled with clip cartridge 150, movement of jaw blade 160 will be arrested, prevented, or otherwise blocked along the longitudinal axis “A” defined by jaw blade 160, shown in FIGS. 6 and 8. Further, vertical movement of jaw blade 160 will be arrested, prevented, or otherwise blocked along axis “B”, shown in FIG. 8, which lies perpendicular to the longitudinal axis “A”. With jaw blade 160 and clip cartridge 150 coupled, during actuation of handle 102 of the actuation mechanism, jaw blade 160 is only capable of transverse motion of the first and second leg members 170, 180 of jaw blade 160 for the opening and closing of first and second jaw sections 192, 194 to clamp or form at least one surgical clip.

As seen in FIGS. 5-7, first and second nubs 152, 154 of clip cartridge 150 may be cylindrical pins. It is envisioned, that first and second nubs 152, 154 of clip cartridge 150 are any geometric shape capable of engaging the shank section 162 of jaw blade 160, such that when clip cartridge 150 abuts jaw blade 160, longitudinal and vertical motion of jaw blade 160 is arrested, prevented, or otherwise blocked.

First and second leg members 170, 180 have a first condition (as seen in FIGS. 4A and 6) and a second condition (not shown). In the first condition, the distal ends 174, 184 of the first and second leg members 170, 180 define a jaw space opening 196 therebetween having a width “JW” (as seen in FIG. 4A). In the second condition the distal ends 174, 184 of the first and second leg members 170, 180 are in close proximity, or in abutting relationship to one another, thus reducing the jaw space opening 196. As seen in FIGS. 3, 4A, and 6, the actuation mechanism is in a pre-actuation condition, the first and second leg members 170, 180 of jaw blade 160 are in the first condition.

The method of applying a surgical clip using the surgical clip applier in accordance with the present disclosure will be described with reference to FIGS. 1-8. An operator is provided with surgical clip applier 100, a clip cartridge 150, and a jaw blade 160. The operator will first insert jaw blade 160 into the open cavity 116 at the distal end 114 of the body portion 110. The operator will next insert clip cartridge 150 into open cavity 116 at the distal end 114 of the body portion 110, such that clip cartridge 150 abuts jaw blade 160 as noted above. Once assembled, longitudinal and vertical movement of jaw blade 160 will be arrested, prevented, or otherwise blocked. Jaw blade 160, when disposed at the distal end 114 of the body portion 110, is operably connected to an actuation mechanism for selective closure of the first and second jaw section 192, 194 upon activation of the actuation mechanism. In one embodiment of the present disclosure, the actuation mechanism of surgical clip applier 100 takes the form of handle assembly 102. Clip cartridge 150, when disposed at the distal end 114 of the body portion 110, abuts jaw blade 160, such that first nub 152 abuts the first end 164 of the shank section 162 of jaw blade 160, and second nub 154 abuts the second end 166 of the shank section 162 of jaw blade 160.

It is further envisioned, in accordance with the present disclosure, that the operator of surgical clip applier 100 will have a variety of surgical clip widths to choose from. Specially, a plurality of clip cartridges 150 are provided, wherein a respective clip cartridge 150 contains a surgical clip “C” having a respective unformed clip width “CW” disposed therein, as shown in FIG. 4B. A plurality of jaw blades are provided, such that width “JW” defined by jaw space opening 196 of the provided jaw blades 160 correspond to the provided variety of unformed surgical clip widths “CW” disposed in the respective clip cartridges 150 provided. Based on the surgical procedure and needs of the operator, the operator selects a specific clip cartridge 150, having the desired unformed surgical clip width “CW” disposed therein. Based on the selected unformed surgical clip width “CW”, the operator selects the jaw blade 160 with the corresponding jaw width “JW”.

In accordance with the present disclosure, a kit will be described with reference to FIGS. 1-9. The kit includes a clip cartridge 150 and a jaw blade 160 in a common package 300 to be used with or in a clip applier, as shown in FIG. 9A. The kit may include surgical clip applier 100, as shown in FIG. 9B. In embodiments, the kit may include a plurality of clip cartridges 150 a-c contained in a common package 300, wherein each respective clip cartridge 150 contains at least one surgical clip “C” having a different unformed surgical clip width “CW” disposed therein respectively, as shown in FIGS. 9C and 9D. The kit may also include a plurality of jaw blades 160 a-c corresponding to the plurality of clip cartridges 150 a-c and the variety of surgical clip widths “CW” provided therein, as shown in FIGS. 9C and 9D. The kit may also include instructions for use 310, as shown in FIGS. 9A-D. The common package 300 may include a thermoformed plastic tray and/or other packaging materials within the view of those skilled in the art.

The various embodiments disclosed herein may also be configured to work with robotic surgical systems and what is commonly referred to as “Telesurgery.” Such systems employ various robotic elements to assist the surgeon and allow remote operation (or partial remote operation) of surgical instrumentation. Various robotic arms, gears, cams, pulleys, electric and mechanical motors, etc. may be employed for this purpose and may be designed with a robotic surgical system to assist the surgeon during the course of an operation or treatment. Such robotic systems may include remotely steerable systems, automatically flexible surgical systems, remotely flexible surgical systems, remotely articulating surgical systems, wireless surgical systems, modular or selectively configurable remotely operated surgical systems, etc.

The robotic surgical systems may be employed with one or more consoles that are next to the operating theater or located in a remote location. In this instance, one team of surgeons or nurses may prep the patient for surgery and configure the robotic surgical system with one or more of the instruments disclosed herein while another surgeon (or group of surgeons) remotely controls the instruments via the robotic surgical system. As can be appreciated, a highly skilled surgeon may perform multiple operations in multiple locations without leaving his/her remote console which can be both economically advantageous and a benefit to the patient or a series of patients.

The robotic arms of the surgical system are typically coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the working ends of any type of surgical instrument (e.g., end effectors, graspers, knifes, scissors, etc.) which may complement the use of one or more of the embodiments described herein. The movement of the master handles may be scaled so that the working ends have a corresponding movement that is different, smaller or larger, than the movement performed by the operating hands of the surgeon. The scale factor or gearing ratio may be adjustable so that the operator can control the resolution of the working ends of the surgical instrument(s).

The master handles may include various sensors to provide feedback to the surgeon relating to various tissue parameters or conditions, e.g., tissue resistance due to manipulation, cutting or otherwise treating, pressure by the instrument onto the tissue, tissue temperature, tissue impedance, etc. As can be appreciated, such sensors provide the surgeon with enhanced tactile feedback simulating actual operating conditions. The master handles may also include a variety of different actuators for delicate tissue manipulation or treatment further enhancing the surgeon's ability to mimic actual operating conditions.

A medical work station generally may include a plurality of robot arms, a control device, and an operating console coupled with the control device. The operating console may include a display device, which may be set up in particular to display three-dimensional images, and manual input devices, by means of which a person, for example a surgeon, may be able to telemanipulate the robot arms in a first operating mode.

Each of the robot arms may include a plurality of members, which are connected through joints, and an attaching device, to which may be attached, for example, a surgical tool supporting an end effector, in accordance with any one of several embodiments disclosed herein, as will be described in greater detail below.

The robot arms may be driven by electric drives that are connected to the control device. The control device (e.g., a computer) may be set up to activate the drives, in particular by means of a computer program, in such a way that the robot arms, their attaching devices, and thus the surgical tool (including the end effector) execute a desired movement according to a movement defined by means of the manual input devices. The control device may also be set up in such a way that it regulates the movement of the robot arms and/or of the drives.

The medical work station may be configured for use on a patient lying on a patient table to be treated in a minimally invasive manner by means of the end effector. The medical work station may also include more than two robot arms, the additional robot arms likewise being connected to the control device and being telemanipulatable by means of the operating console. A medical instrument or surgical tool (including an end effector) may also be attached to the additional robot arm. The medical work station may include a database, in particular coupled to the control device, in which are stored, for example, pre-operative data from the patient/living being and/or anatomical atlases.
